v GANG-PLOW.

proved means whereby the plow may be adjusted to, raise or lower thepoint to give the plow the desired suction. This I accomplish byproviding means for adjusting the standard upon the lower end ofwhichthe plow is carried. 1 v

- Another object is to provide a construction in which theplow may beheld in position by means of abreak pin for use in ground whereobstructions are likely to be met, the

plow beingpermitted to swing backward out of;the ,wayof any obstructionand thus saving-it-fircm injury or; breakage. In the construction shown,the break pin is used in the. connection between the plow standard andthe'pIoW' beairn the construction being suclrjthat'the -standard mayeither be held idworln'ngposition bynieans of the break pin or be fixedin position Without the use of a break. pin if desired. I v. Thisapplication is a divisional application, the subject-matter shown andclaimed herein-having been disclosed, described and originally inapplication for patent on gang plows Ser. No. 525,720, filed by me onNovember 1, 1909, and subsequently divided out of said application.

In the drawings:'Figure 1 isa side view of a plow beam connected in anysuitable manner to a bracket forming part of the draft frame of-a gangplow. Fig. 2 is an enlarged detaiI partIy in section, showing the'meansfor connecting the plow standard to, the plowbeams one ofthe plow beamsbeing removed better to show the construction, the'connection beingmade'by means of a break pin. Fig. 3 is an enlarged detail showing'theposition the parts shown in Fig. 2 may assume when the break pin isremoved .or broken. Fig. 4:- is an enlarged detail, being a view fromthe left of the parts shown in Fig. 2, partially in vertical fcross-section. Fig. 5 is an enlarged detail,

Specification of Letters Patent. n Patented 16, 1911. Originalapplication filed November 1, 1909, Serial No. 525,720. Divided and thisapplication filed February 24, 1910. Serial No. 545,656.

F 8 indicates 'a bracket forming part of the. draft frame of a gangplow, towhich: are secured by means of a pin 9 coupling de vices 12 ofany approved type bymeans of which plow beams 10'1l'are adapted to beconnected to the draft frame. I 1

13 indicates a bolt which passes through openings in beams 10-11 andserves" to brace said beams more firmly together;

in my application for patent'on-gang plows above'referred to, inwhichthe standard 15 turn and in which the gage wheel is adapted in turn, 'isadapted to be swung on the standard 15 and set-in any desired positioiiL14 indicates a gagewheel mounted below the beams 1011 in any approvedmanner,-

preferably in the manner shownand claimed 7-0 uponwhich the wheel ismounted is free to It is not-believed to be necessary to furtherdescribe this mechanism herein, as it forms no part of thepresentinvention.

17 indicates a plow standard having secured upon its lower end inany-suitable manner a plow 18 of any approved type. As'

shown in dotted lines in'Fig. 3, the upper end of the standard 17 iscurved forward and, as shown in Figs. 3 and 4, has secured upon it ateach side a plate 19. These plates 19 are separate from each other andseparate from the standard 17 and are secured in position on thestandard by means of a bolt 20 and rivet 21, but they'may besccure'd in"place in any other suitable manner withoutdeparting from my invention.As shownin Fig. 1, the front end of the standard and plates '19 areadapted to be secured 'in posi tion between'the beams 10-11' by'a bolt22) Referring now to the means by which the 1 plates are secured betweenthebea'nis 10'11 at their rear ends so as to be permitted to swingpivotally thereon when a'break pin is" used and so that the angle of thestandard plow either when 'a break pin' is used or 'when the standard'is fixed rigidly in place,

may be adjusted to vary thesuction' of the 24 indicates a yoke whichstraddles the plates 19, 'in the construction shown, each arm of theyoke being located between one limited up and down movement relative tothe yoke and relativeto the beams.

26indicates a set-screw screw-threaded in the end of the yoke 24: andbearing at its lower end against the plates l9,being thus adapted tolimit the upward movement of therear ends of the plates as desired. Theplates 19 being secured .at their forward ends against verticalmovement, a slight vertical movement of the rear ends of the plates willsuffice to change the angle at which the standard 17 stands, changingaccordin ly the position of the plow, as will be rea ily understood. e

1 27 indicates holes through the beams 10-41 in advance of the holes inwhich the bolt 22 is shown in Fig. 1, through which holes the bolt 22 isadapted to be passed when a break pin is to be'used, as shown in Figs. 2and 3, said bolt in its changed loca tion being indicated by 22*.

l 28 indicates a lug on the front face of each of the plates 19 adaptedto bear against the bolt 22 and adapted to prevent upward movement ofthe front ends of the plates 19' relative to the beams. 29 indicates a.break pin extending through suitable holes in the plates 19, the holesbeing so positioned that the pin 29 extends across the upper edges ofthe beams 10-11. This pin normally holds the front ends of the platesagainst downward movement relative to the beams, butiwhen an obstructionis met by the plow the pin is-adapted to break and permit the plow toswing back ward on the bolt 25 as a pivot, thus preventing any unduestrain upon or breakage ofthe parts other than the pin.

per end, a plow mounted on the lower end What I claim as my inventionand desire to secure by Letters Patent is,-

1. The combination of a draft frame, plow beams pivotally connected attheir front ends with said draft frame, a standard extending forwardalong said beams at its upof said standard, means for'pivotally,connecting said standardat the rear endsof said beams, and a break pinholding the forward end of said standard normally against movementrelative to said beams, said pivotal connections comprising a boltpassing through slotted openings and means or holding said bolt atdifierent adjusted positions in said slots.

2. The combination with a draft frame,- plow beams pivotally connectedat their front ends with said draft frame, a standard pivotallyconnected at its upper end. with said plow beams, said standard beingprovided with a slot arranged in the position of an arc about'thepivotal point of said standard, a bolt passing through said beams andthrough the slot in said standard, a. yoke pivotally mounted on saidbolt, a set-screw in'said yoke adapted to bear upon said standard inanyadjusted position-relative to said beams and to hold the standardagainst movement in one direction, and a plow carried on said standard.

3. The COIIlblIlttblOn with a draft frame,

two plow beams connected at their front ends with said draft frame, astandard, side plates on the upper end of said standard and adapted tobe embraced between said plow beams and provided near their rear endswith substantially vertical slots, a yoke adapted to straddle saidplates between the same and thetwo plow beams, a bolt passing throughsaid beams through said yoke and-through the slots in said plates, anda. set screw in said yoke 2 "lapted b its-movement to vary the angularrelation of said. standard to said plow beams.

4:. The combination with a draft frame, two plow beams connected attheir front ends with said draft frame, a standard, ":de plates ontheupper end of said standard and adapted to be embraced between said lowbeams and provided near their rear ends with substantially verticalslots, a yoke adapted to straddle said plates between the same and thetwo plow beams, a bolt passing through said beams through: said yoke andthrough the slots in said plates, and a setscrew in said yoke adapted byits movement to vary the angular relation of said standard to said plowbeams, the forward ends of said plates being adapted to carry a breakpin bearing upon the upper surface of said 'plowbeams.
